To all whom t may concern.'

Be it known that I, HOWARD R. HIGGINS, a citizen of the United States, residing at Glen Ellyn, in the county of Dn Page and State of Illinois, have invented a newand useful Improvementin Dustproof B earings, of which the following is a specification.

This invention relates to dust-proof bear ings and the like and is fully descrlbed 1n the following specification and shown 1 n the accompanying drawing, in which the Figure shows a partial longitudinal sectlon through a bearing embodying the invention.

In the embodiment illustrated, thebearing is mounted on an axle 10 having a slightly enlarged cylindrical yportion 11I upon which is fitted, in the usual manner, the inner race member 12 of a combined radial and thrust ball bearing, the outer race 0 member 13 of which is mounted in a bore 14 and normally held against a shoulder 15 by an outer ball bearing V(not shown), which may be mounted in any well .known manner. l An enlar ed cylindrical portion 16 1s formed insi e of the cylinderical portion 11, which is separated therefrom by a shoulder 17. A plate 18 is held between this shoulder 17 and the inner race member 12.

An annular member 19 has a cylindrical portion 20, which is snugly fitted into the bore 14 and, if desired, may belocked therein by means of screws 21. A plate 22,

preferably of Z-shaped cross section, lies loosely within the cylindrical portion 20 forming an annular pocket in which the felt washer 23 is held.4

Another felt washer 24 .of larger diameter is concentric with the axle 10 and lies between the cylindrical portion 20 and the cylindrical portion of the Z-shaped plate 22.

This felt washer bears against the late 18,

thereby forming a seal which, toget er with the seal formed between the felt washer 23 and the cylindrical portion '16 of the axle 10,

revents oil within the bearing from workmg out and at the same time'prevents dust I on the outside from getting into the bearin The screws 21 permit of the take-up and a justment of the pressure between the washer. 50 24 and'the plate 18 as wear occurs. 4

While I have shown and describedcertain.

` embodiments of my invention, it is to,l be understood that'it is capable of 'many' modificat-ions. Changes,l therefore, in thev con-v DUSTPROOF BEARING.

struction and arrangeme ,'.may-befmade without departingjfro'mthe spirit andfscop'e of the invention as disclosed in the appended claims, in which it iis Inyintention to cla-im.

all novelty inherentin `my invention as broadly as possible in view ofthe prior art.

What I claim as new and desire tosecure by Letters Patent, is:

.1. In combination, an axle having a -cylindrical surface at the inner end, a wheel journaled thereon, a portion ofsaid wheel surrounding said cylindrical surface, a feltv washer adapted to slidably l surround said .said portion, an anti-friction bearing having inner and outer race members, the outer race member being fitted within said bore, the

inner race member being tted upon said' axle, an annular member snugly fitting within said bore and acting as a closure for the outer race member, sald annular member re- 4cylindrical surface, a cylindrical Abore within naled thereon, a portion of 4said wheel surroundlng said cylindrical surface, a felt washer adapted to surround said cylindrical surface, a cylindrical 'bore within said portion, an anti-friction bearing having inner and outer race members, the outer race member being fitted within said bore, the inner race member being fitted upon said axle, an annular member snugly fitting within said bore and acting as a closure for the space between the bore and axle, said annular member retaining y said felt washer, a plate of Z-shaped crosssection encloslng the circumference Aand one end of the felt washer, a second felt washer lying` outside the first mentioned felt` washerand separated therefrom by said plate of `Z-shaped cross-section, and a plate carried by said axle bearing against said second felt washer.

3. `In combination, an axle having a cylindrical sur/face at the inner end, a wheel ]our naled thereon, a portion of said wheel surrounding said cylindrical surface, a felt washer adapted to slidably surround saidy cylindrical surface, a cylindrical bo-re withvin said portion, an anti-friction bearing having inner and outer race members, the outer race member being fitted Within said bore, the inner race member being fitted upon said axle, an annular member snugly fitting 'Within said bore, a second felt Washer outside the 5) first mentioned felt Washer and separated therefrom by a curved plate, a plate carried by said axle and bearing against said second felt Washer, and additional means for retaining said annular member Within said 10 bore.

4. In combination, an axle having a cylindrical surface, a Wheel journalled on said aXle,'a portion of said Wheel surrounding said cylindrical surface, a substantially plane surface' adjacent said cylindrical surface and 15 perpendicular thereto and affixed to said axle, a member carried by said Wheel and felt Washers carried by said member and having sliding bearing upon said cylindrical surface of the axle and plane surface to pre- 20 vent dust from entering the bearing.
